2017-07-25ash: [REDIR] Replace GPL noclobberopen code with the FreeBSD versionDenys Vlasenko
Upstream commit: Date: Thu, 10 Mar 2011 16:52:13 +0800 [REDIR] Replace GPL noclobberopen code with the FreeBSD version Replace noclobberopen() from bash with the FreeBSD code for noclobber opens. This also reduces code size by eliminating an unnecessary check.

2017-07-25ash: sync up with dash with respect to redirection escapingDenys Vlasenko
We fixed the problem differently than they. Let's not deviate. Upstream commit: Date: Thu, 27 May 2010 20:07:29 +1000 [EXPAND] Fix corruption of redirections with byte 0x81 In other ash variants, a partial implementation of ksh-like cmd >file* adds and removes CTLESC bytes ('\x81') in redirection filenames, preserving 8-bit transparency. Long ago, dash removed the code to add the CTLESC bytes, but not the code to remove them, causing corruption of filenames containing CTLESC. This commit removes the code to remove the CTLESC bytes. The CTLESC byte occurs frequently in UTF-8 encoded non-Latin text. This bug has been reported various times to Ubuntu and Debian (e.g. Launchpad Ubuntu #422298). This patch is the same as the one submitted by Alexander Korolkov in Ubuntu #422298.

Upstream commit: Date: Tue, 25 May 2010 20:55:05 +0800 [VAR] Move unsetvar functionality into setvareq This patch moves the unsetvar code into setvareq so that we can no have a pathological case of an unset variable hanging around unless it has a bit pinning it like VEXPORT.
